# How is electrical current measured?

Ampéres( french for amp )

**Amps :) ( For short :P )**

### What is an electrical resistor?

An electrical resistor is a device that resists the flow of electric current. It is measured in Ohms and the resistance in a circuit can be related to voltage and current flow by the equation v=ir, where v is the voltage, measured in volts, i is the current, measured in amperes, and r is the resistance.

### How to convert ohms to ampere?

You can't. That would like converting an apple into an apple basket. An Ohm is a measure of resistance to electrical current going through a circuit. The amount of electrical current is measured in Amperes. (The pressure that pushes the current through the circuit is Electromotive Force, or EMF, and is measured in Volts.

### What relation of voltage and current?

Current is directionally proportional to the applied voltage and inversely proportional to the resistance of the circuit. <<>> EMF (electromotive force) is measured in Volts. Current is measured in Amperes. Like water pipes, EMF (or voltage) is the "push" or pressure in an electrical circuit. Current is like the gallons per minute . . . it is the "amount" of electrical flow.

### What is the name for what flows in an electric circuit?

A flow of electrons in an electrical circuit is called a current, which is the name given to the amount of electrical charge flowing in a certain period of time. Any total quantity of electrical charge is measured in coulombs. Any flow of electrical current is measured in amps. 1 amp is equal to a flow of 1 coulomb of electrical charge in one second of time.

### What is resistance in a circuit?

The technical definition is "Electrical resistance is a ratio of the degree to which an object opposes an electric current through it, measured in ohms." In simplfied terms, electrical resistance is broadly equivalent to friction in a mechanical system. If you applied a voltage to a circuit with zero resistance then you would get an infinite current. In reality all circuits have some resistance which limits the current. We can predict the current in a…
